The monoclonal antibody 203/14F11 specifically recognizes human leukotriene B4 receptor 1 (BLTR-1). BLTR-1 is a seven-transmembrane, G-protein-coupled receptor. The receptor plays an important role in pro-inflammatory responses. Leukotrienne B4 receptors are distributed in various hematopoietic cells including monocytes, granulocytes, and lymphocytes. Leukotriene B4 (LTB4), a product of arachidonic acid metabolism, is the ligand for BLTR-1. The immunogen used to generate 203/14F11 hybridoma was a human BLTR-1-transfected cell line.
The antibody was conjugated to BD Horizon BUV615 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome with an Ex Max near 350 nm and an Em Max near 615 nm. BD Horizon Brilliant BUV615 can be excited by the ultraviolet laser (355 nm) and detected with a 610/20 filter and a 595 nm LP. Due to the excitation of the acceptor dye by the blue/yellow-green laser line, there may be significant spillover into channels detecting PE-CF594 like emissions (eg, 610/20-nm filter).
